NON-BLINDING DEVICE.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed February 17, 1915. Serial No. 8,701.

To all whom it may concern:

Be it known that I, EUGENE ADERENTE, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented a new, simple, and useful device namedNon-Blinding Device, for the controlling of the rays of glaring(blinding) lamps, of which the following is a specification.

This invention relates to a device adapted to be applied to high powerheadlights for automobiles and the like, the device being preferably,although not necessarily, in

the nature of an attachment applied to the glass of the lamp for thepurpose of so influencing the rays that they will practically all bedirected on the road or street surface without producing any blindingeffect upon pedestrians or occupants of other vehicles, since the raysof light are directed forwardly in a line below the ordinary level ofsight. I

- The invention has for its general objects to provide a comparativelysimple, inexpensive audefl'ective non-blinding device for lamps which isof such design as to be housed within the reflector and prevent rays oflight from being directed Skyward, while utilizing such rays bydeflecting them downwardly on the road surface, the device consisting ofa plurality of horizontally disposed spaced bars which may be silvered,nickel plated or otherwise formed into reflectors, and the bars are sodesigned and arranged that the rays of light from the lamp within thereflector can be directed forwardly, some between the bars of thedevice, without reflection, and some by reflection from one bar toanother.

A more specific object of the invention is the provision of anattachment for headlights, the attachment being in the form of a ringhaving parallel horizontal strips of thin metal disposed with their flatsurfaces in a horizontal plane so that rays of light can passhorizontally forwardly, and the rear edges of the bars being bentupwardly, whereby rays of light striking the under sides of theupwardly-bent portions will be deflected downwardly against the uppersurfaces of said portions, whereby the latter will reflect the rays oflight forwardly in a horizontal direction, and preferably the adjacentreflecting bars will be so spaced apart that rays reflected by theparabolic reflector can pass forwardly between the bars without beingreflected by the latter, so that the attachment constitutes a devicewhich not only prevents blinding of pedestrians and occupants ofvehicles, but more brightly illuminates the road surface or materiallyincreases the effective power of the lamp.

.With such objects in View, and others which will PPear as thedescription proceeds, the invention comprises various novel parts whichwill be set forth with particularity in the following description andclaims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, and wherein similar characters of reference indicatecorresponding partsin both the views, Figure 1 is a vertical section ofa lamp with the non-blinding device applied thereto; and Fig. 2 is afront view of the lamp and attachment.

Referring to the drawing, A designates a reflector and B the lamp of aheadlight which has the usual glass front.

The attachment comprises a plurality of connected sheet metal horizontalbars C set edgewise in ahorizontal plane, each bar having its rearportion throughout its length bent upwardly at an angle of approximatelyfifty degrees, these bars having their ends connected with a ringfitting the reflector, and they are disposed directly behind the glassfront of the headlight. These bars serve as reflectors and hencethey'are on both sides silvered, nickel plated or otherwise formed intoreflecting elements. The upper edge of the upwardly-bent rear portion ofeach bar or strip is disposed below the level of the straight horizontalportion of the adjacent bar above, so that ample space is provided forthe passage of the rays that are reflected forwardly by the parabolicreflector A, this effective space for direct reflection of rays from thereflector being indicated by the letter D, Fig. 1. Theangularly-disposed reflecting portions of those bars lying above thefocal axial line of the reflector receive 6-5 features of constructionand arrangement of upper surfaces of the said portions, and these inturn reflect the rays forwardly from the headlight in a horizontaldirection. Thus it will be seen that practically no rays are lost and norays can be emitted skyward or in such a manner as to have a blindingeflect upon persons in front of the headlight with the eyes above thelevel thereof.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of operation willbe readily under stood by those skilled in the art to which theinvention appertains, and while I have described the principle ofoperation, together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative and that such changes may be made when desired asfall within the scope of the appended claims.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent.

1. The combination of a headlight includ ing a source of light, and aplurality of reflector bars disposed in front of the said source andhaving upwardly-bent rear edges for receiving upwardly radiated lightand directing it horizontally.

2. The combination of a reflector, a source of light disposed in thefocal center thereof, and a plurality of reflecting bars arranged infront of the source of light and spaced apart to permit the passage ofrays of light from the lamp and from the reflector, said bars havingupwardly-bent rear portions whereby rays of light striking the rearportion of one bar will be reflected upon the rear portion of anadjacent bar and thereby reflected forwardly.

3. An attachment for lamps, comprising a ring having parallel reflectingbars spaced apart, the rear edges of the bars being bent upwardly inparallel relation.

4. An attachment for lamps, comprising a ring having parallel reflectingbars spaced apart, the rear edges of the bars being bent upwardly inparallel relation, the upper edge of the upwardly-bent portion of onebar being wholly below the superimposed adjacent bar.

5. The combination of a reflector, a source of light disposed at thefocal center thereof, and a plurality of reflecting bars arranged infront of the source of light and spaced apart to permit parallel rays oflight from the lamp and reflector to pass Without reflection by thebars, each bar having one edge bent out of the plane of the bar, thebent edges of all the bars being parallel, and the bent edge of one barbeing spaced from an adj acent bar, and both surfaces of the bentportion of each bar being a reflector, whereby rays striking one barwill be reflected against an adjacent bar and thereby reflected parallelwith the rays of light passing directly between the bars from the lampand reflector.

EUGENE ADERENTE.
